This story is now AU. I still don't own Harry Potter.

September 19, 1919

"She's so tiny," John Sharp said as he held his tiny daughter in his arms. He turned to his wife, who was relaxing on the bed behind him. "I don't know how I can love something so much and only just been introduced."

"She's a part of you," Samantha said from her position on the bed. "That's how. And she a part of me too, and you love me."

John smiled as he carefully handed the newborn to his wife. "I'm so glad that the JR Corporation is so advanced," he said as his daughter held his finger in her hand. "I wouldn't have wanted to think about you trying to have our baby anywhere else."

He kissed his wife's forehead and smiled down at her. "I love you so much."

She smiled. "I love you too, and now our daughter. I love you Adiana."

A knock at the door startled them both. "I'll get it," John said standing and walking to the door. Samantha felt her heart begin to pound. Something wasn't right. She held Adiana closer to her.

John opened the door to find a man with dark, almost black hair, and green eyes standing there wearing a business suit. Behind the man was a small boy, no older than three, with black hair, but the lightest brown eyes John had ever seen. The boy was dressed in slacks and a button-up shirt with his hair in a mess.

"Chairman Director? How kind of you to come visit. Honey, It's Mr. Riddle and…a young boy."

Jeremy Riddle Sr. laughed as he entered. "This is Thaddeus Snape. His father used to work for me until he died. His mother has also passed on and I decided to take him in rather than have him sent to an orphanage."

Jeremy turned his eyes to Samantha on the bed, and the small bundle in her arms. "So, this is the newest addition to the family, how wonderful. I hope that she has your sunny disposition Samantha…and your firm hand, John."

"Thank you Mr. Riddle." John moved back to his wife. "She is the most perfect baby in the entire world."

Jeremy smirked. "I know."

Moments later several armed guards entered the room. Their weapons out and aimed at the family. Samantha held tighter to Adiana seconds before her child was ripped from her hands. Jeremy stood there holding her child.

"Mr. Riddle!"

"I hate that it was you who had such a…remarkable child. It will be difficult to find such a wonderful secretary, and chief security officer." Jeremy turned and handed the child to Thaddeus. "Let's go Thaddeus. I hate waiting to start my work."

The two left the room and started down the hallway. The baby in Thaddeus' small arms was crying. Seconds later several gunshots rang out and the child grew silent, almost like she knew that her parents couldn't save her anymore.

Minutes later they arrived in the lab. "Thaddeus, place her in that chamber there, carefully," Jeremy said as he put on a white coat. Thaddeus did as he was told and placed the baby in a small box-like chamber, just big enough to hold a newborn baby of reasonable size.

Thaddeus took several steps back and watched with sadness in his eyes as Jeremy began to analyze her blood and her body.

After what seemed like hours the results were in, and Jeremy seemed giddy with happiness. "She's perfect. Her natural paranormal abilities will already be strong, and with a bit of training and my special formulas, her strength and mind will also increase. She is the perfect candidate for becoming the ultimate biological weapon." He turned to Thaddeus. "And with you as her partner, the two of you will be unstoppable." He laughed as he turned to leave the room.

"What a great day for the JR Corporation!"

Thaddeus waited until Jeremy had left the room, locking the door behind him as he went, before walking up to the newborn that was currently crying her eyes out.

He gently rubbed her stomach. "Don't cry," he said. "I swear to you that one day we will both be out of here. I'll take care of you."

The baby opened her eyes, which were currently a startling blue, and her crying stopped. She was no longer upset as she looked up at Thaddeus.

"I have to go to bed now," he said softly, "but I will return in the morning. Sleep now, for tomorrow your life as a guinea pig begins. I'll see you in the morning."

The baby closed her eyes and fell asleep, almost like she was in a trance of some sort. Thaddeus leaned down and kissed her forehead before softly whispering, "Good night Adiana," and slipping off to bed.

Little did he know that behind a two-way mirror, Jeremy Riddle had seen the whole exchange with a knowing smile.

September 21, 1919

A baby's cries filled the room as Jeremy watched as the drug he had just injected begin its changes.

Her skin changed colors from the pink to green to blue and then back to pink again. Her cries began to lessen as the pain from the changes began to recede.

Jeremy's eyes widened in excitement as Thaddeus watched the entire thing with saddened eyes. "Isn't this great?" he said with a smile. "Every single injection has been successful. Now to put this new one to the test."

Jeremy pulled out a small gun and aimed it at the child. Thaddeus looked shocked as he moved in the way. "What is wrong with you? What if the experiment doesn't work?"

Jeremy shrugged. "Then she'll die."

Thaddeus attempted to stay in the way when suddenly Jeremy pushed him out of the way, aimed, and fired. "Stop!"

The bullet flew through the air and then bounced off an invisible shield around the baby. The bullet flew back and hit Jeremy in the leg.

"Damn it!"

Thaddeus looked from the bloody leg that Jeremy was currently holding onto back to the child on the table. "Adiana?" he said in a soft voice.

Jeremy glared at both children before limping to his table and pressing a small button. Seconds later a medical crew arrived and began work on Jeremy's leg.

"While the experiment was successful," Jeremy said, "this little mishap with not go unpunished. I'll just have to give her…that special serum."

Thaddeus' eyes widened before he moved to the baby quickly. "No! Please don't! She's just a baby and doesn't know any better."

Jeremy stood, despite protests from the doctor, and pulled a rather large needle from his desk, already filled with a strange blue liquid. "She will learn to be more careful in the future, believe me."

Jeremy pushed Thaddeus to the floor violently, knocking the boy out as his head hit the floor, and injected the serum into the baby. "Sweet dreams."

Seconds later, Adiana was out, locked in a paralyzing sleep.

March 24, 1932

Jeremy smiled at the two young teens before him. After years of work, it was time for a test run of his perfect weapons.

"Today the two of you will prove to me just how great a job I'm doing here. You will take out our competitor, Baskettes Corp. and bring me their designs for a new type of military weapon. If you fail…well, then I'll have no choice but to terminate the project, and the subjects."

Thaddeus looked over at Adiana. Her usually kind eyes now filled with malice and hate. He knew that his too looked just the same, an act to fool the man in front of them.

"Get going!" Jeremy said with a smile. The two left, each hoping that today was the one day that the Baskettes Corp. employees were all sick in their beds.

July 3, 1933

Thaddeus and Adiana looked up at their new home. It was Jeremy's family home…at least that is what they had been told.

It was time to start the new training.

They walked up the steps, their movements being carefully monitored by their transfer officers that Jeremy had assigned to them.

The moment they entered the elaborately decorated entryway both felt something go through them.

"So sorry about that," a voice called out. Both Thaddeus and Adiana looked up to see who had spoken to them.

It was Jeremy Riddle, in all his glory, dressed in his finest. Standing next to him was his young son, not too much younger than Adiana himself.

"My son, Jeremy Jr., is going to over see your training here."

The barely 12-year-old boy stared at Adiana in a rather uncomfortable way. Adiana could feel him trying to undress her with his eyes.

It disgusted her.

December 24, 1934

"Congratulations!"

Adiana hugged Thaddeus tightly before transferring her hug to his wife, the love of his life, Gwendolyn.

The dark haired, onyx eyed beauty smiled as she returned the hug to the "sister" of the man she loved.

The entire wedding had been perfect, even if the bride's family wasn't in attendance. Strangely enough the JR Corporation was willing to pay for the whole thing, which worried Adiana, but that was a worry for another day. This was a happy day.

Adiana smiled widely at the man she considered her brother and dearest friend, standing there with his wife. She could feel the love the two had for each other.

Nothing could ruin such a perfect love.

January 4, 1938

"You're wife and son were a liability. We couldn't have someone like yourself, an important cog in our machine here, have weaknesses."

"You son-of-a-…"

"I wouldn't finish that sentence if I were you," Jeremy said. He pushed a button on his desk and instantly Adiana was pulled against the wall, pinned there and unable to breath properly.

"Thaddeus!" she said loud enough to get his attention. He turned and moved towards her, all with the intention of helping her.

"Stop!" Jeremy said loudly. Thaddeus stopped, his brown eyes narrowed on Jeremy.

"Let her go," he said calmly. Jeremy laughed obviously glad about what was going on.

"Not likely. She is JR property, just like you."

Thaddeus growled slightly, but didn't move.

"And now we add your dear son to the happy family," Jeremey said with a smile. "He's young enough that we can recreate another you."

Thaddeus was obviously fighting every instinct he had to go for the man's throat. His fists clenched and unclenched at his sides.

"Unless you promise to obey us and not to marry again, your son will remain unaltered. Family is a liability, a weakness. That is why neither of you have one…anymore."

Adiana's eyes widened as Jeremy walked back to his desk and pressed the release button, sending Adiana to the floor in a heap. She stood and glared at him.

"Damn you," she said in a strong voice. The Chairman laughed as he seated himself.

"Your next assignment is waiting for you, leave me."

Thaddeus and Adiana left the room, both in a rather sour mood. Adiana didn't know what to say.

"I'm sorry about Gwen," she said finally, "but at least Tobias is still alive."

"And you," Thaddeus said finally. Adiana smiled at him. "You are like family to me Adiana. We grew up together. You are like a sister to me, like I've always told you and I would do anything for you. You and Tobias are my family now. I want you to promise me something, as my sister."

"Anything," Adiana said firmly.

"Promise me that if anything happens to me that you'll get Tobias away from here. Don't let them do to him what they did to us. I don't want him to get a single dose of any kind of experimental drug like the kind they give us every chance they get."

"Nothing is going to happen to you." Adiana said with a firm resolve, "but I do promise you that if anything happens I will take care of your family for as long as I live."

Thaddeus pulled Adiana into a brotherly hug. "Thanks Adiana. I knew I could count on you."

January 7, 1938

"Thaddeus was more of a man than you will ever be. And since you took his life, I take yours. For his wife you took and the family you tried to take from me I'll take that lives of your men…and one day your own family. Your heir will one day fall at my feet, Jeremy Riddle."

Those were the last words Jeremy heard as he hit the floor, dead.

Adiana moved from Thaddeus' dead body and quickly through the hallways of the JR Corporation building. She would randomly snap the necks of people who came too close to her. A few tried shooting at her, but they too ended up dead.

Finally she reached the nursery. She could see Tobias lying safely in his bed. She moved across the room and carefully lifted him into her bloody arms. His blanket soaked up the blood as she held him.

She smiled down at him, her eyes now reverted back to their original brown hazel color. "Come on, let's go home now."

Present Day

"From that day on I hid with Tobias. Then on the anniversary of Thaddeus' death, I made a mistake. Tobias was three and wanted to know where his parents were. So, I took him to the graveyard, and that's where we were discovered.

"I managed to escape then, but knew it was a matter of time before they found us again. I did the only thing I could. I took Tobias to his Aunt Abigail, Gwendolyn's only relative to condone the wedding between her and Thaddeus, and left him there.

"Then I allowed myself to be caught."

Adiana took a deep breath as she came to the end of her story.

"After months of torture and pain it was decided that I should be cryogenically frozen until I could be controlled. That was the last I remember until Dumbledore opened the chamber and I was awoken."

The room was silent as everyone took in what they had just heard. The silence was only broken by a groan from the man on the couch, Severus Snape, the last living descendant of Thaddeus Snape, Adiana's partner, best friend, and "brother."
